Be9(d,p),(d,t),(d,a)反应研究

本文在E_d=0.1—2.5MeV能量范围内,研究了Be⁹(d,p₀)Be¹⁰(0),Be⁹(d,p₁)Be¹⁰(3.368MeV),Be⁹(d,t₀)Be⁸(0),Be⁹(d,α₀)Li⁷(0)及Be⁹(d,α₁)Li⁷(0.478MeV)诸反应。在E_d=0.150,0.220,0.401,0.706,1.005,1.301,1.484,1.750,2.000,2.250和2.500MeV共十一个能量上分别测量了这五群出射粒子在θ_L=10—155°区间的角分布。在θ_L=135°,E_d=0.1—2.5MeV,在θ_L=95°,E_d=0.1—2.2MeV,和在θ_L=112.5°,E_d=0.5—2.5MeV测量了Be⁹(d,p₀)Be¹⁰的激发函数。在θ_L=135°和112.5°,E_d=1.2MeV,用较厚靶(100—300μg/cm²)测量了Be⁹(d,p₀)Be¹⁰(0)反应的截面绝对值,结果为σ_(p0)(θ_L=135°)=1.60mb/sr,σ_(p0)(θ_L=112.5°)=1.55mb/sr。这样就得到了在此能区内,这五群出射粒子的截面情况。对所得结果进行了一些讨论。

STUDIES OF Be9 (d,p), (d,t) AND (d,α) REACTIONS

The reactions of Be⁹(d, p₀)Be¹⁰(0), Be⁹(d, p₁)Be¹⁰(3.368 MeV), Be⁹(d, t₀)Be⁸(0), Be⁹(d, α₀)Li⁷(0) and Be⁹(d, α₁) Li⁷ (0.478 MeV) have been studied at deuteron bombarding energies from 0.1 to 2.5 MeV. The angular distributions of these five groups of outgoing particles have been measured respectively between θ_L = 10°and 155°at eleven bombarding energies of 0.150, 0.220, 0.401, 0.706, 1.005, 1.301, 1.484, 1.750, 2.000, 2.250 and 2.500 MeV. The excitation functions of the Be⁹ (d,p₀) Be¹⁰ reaction have been measured at θ_L = 135° from E_d = 0.1 to 2.5 MeV, at θ_L = 95° from E_d = 0.1 to 2.2 MeV and at θ_L = 112.5° from E_d, = 0.5 to 2.5 MeV, respectively. By use of thicker targets (100-300μg/cm²) and at E_d = 1.2 MeV, the absolute cross sections of the Be⁹(d, p₀)Be¹⁰ reaction were measured at θ_L = 135°and 112.5°; the results obtained are: σ_(p0)(θ_L = 135°)= 1.60 mb/st and σ_(p0)(θ_L = 112.5°)=1.55 mb/st. Thus, the behaviours of the cross sections of all these five groups of outgoing particles have been obtained in this energy range. These experimental results are discussed to some extent.
